The holidays are are almost upon us, and no celebration would be complete without some glowy LED lighting! Sign up for our BlinkyTile Christmas ornament workshop this Saturday to build your own blinky LED ball using BlinkyTiles. Makes a perfect tree topper or gift for the disco enthusiast in your life!
Thanks to world class blink master Matt Mets we have stickers again, hand delivered from the far side of the world. If you are by our OPEN craft night tonight, or any Thursday really, pick a couple up and be swankier than you already are.
By day, I tell computers what to do. I like to think that I’m okay at doing that. On the weekend, I sometimes make radio things or build off-the-wall electronics projects at Resistor. I’m not quite as okay at that. It’s quite rare, though, that I make something tangible which has no physical function other than its own form. Long ago, I watched my grandfather build things out of wood: tables, benches, once even a dollhouse. Recently, my friends welcomed their son into the world, and as the holidays are approaching I thought a perfect gift would be a set of wooden blocks made by hand. I thought it would be a perfect opportunity to dabble in woodworking and create something completely non-electronic, non-code for a change.
Join us this Saturday, December 13th, at 1-4pm as we dump our hoards of paper out on the table and make a bunch of things out of it!
Tickets are $10 here: https://www.eventbrite.com/e/make-along-paper-holiday-cards-tickets-14889423667?ref=ebapi
Things you can work on (and which we can help you with) at this Make-Along are:
Holiday Cards, All Occasion Cards, Book Binding, Pop-Ups, Paper Sculptures and objects, Automata, Origami, Kirigami, Gifts for Mommy, Paper electronics-y, and who knows, maybe we will bring some potatoes and rubber erasers for doing some fun+cheap printmaking (oh right we also have an intaglio press if you want to get fancy).
Bring your own paper and tools OR come use ours, we have a lot. Never used an X-Acto before? We can teach you! Scared of paper cuts? We have lemon juice for that! Just kidding, that stings. Neosporin is what you want. Lemon juice makes a fun invisible ink though, maybe you want to try that instead. Just put a band-aid over your paper cuts first.
We are also offering a special Make-A-Long Pass that will give you (or a loved one) access to all of next year’s Make-A-long workshops – a $120 value for just $75. Get ready for another Nail Art Make-Along in January!
Who is running this Make-Along?
Shelby Arnold – a professional paper engineer in the studio of Robert Sabuda (fancy words for pop-up book designer) and amateur bookbinder. She also plays with paper electronics and paper clockmaking.
Colleen AF Venable – a professional book designer and lover of tiny handmade books, from mini-comics to zines. She just finished art directing a two foot tall paper craft book with Workman Publishing on making giant paper machines—like diggers, trucks, dirigibles—with moving parts. She really likes the word dirigible.
Join us for a two part discussion on Bitcoin by Andrew Sheppard. Andrew (“Shep”) is a consultant on Wall Street who works in the areas of Big Data and Big Compute. He is also a part-time professor teaching on the Masters in Financial Engineering (MFE) program at Baruch College.
Bitcoin is a new form of electronic cash growing in popularity. As a system it is a protocol, a P2P network, and a bunch of cryptographic algorithms. Oh, and add a new form of global currency to that list. In short, Bitcoin is a bundle of technology and economic concepts all rolled into one.
Bitcoin is also like the tooth fairy: most have heard about it, but few have actually encountered it for real. And even those who have actually encountered Bitcoin don’t really know what it is at a basic (read “fundamental”) level; in particular, too emphasis is placed on the technology and not enough on the economics of Bitcoin, though both are highly novel. This talk remedies that.
Want to drive more LEDs with fewer IO pins? Then you might be interested in the Charlieplexing technique. I’ve written an example sketch can drive six LEDs each with 8-bit PWM using the three IO pins on the Adafruit GEMA microcontroller and is a fairly easy sewable LED sequin project since there are no crossed wires when it is stitched with conductive thread. Enjoy the short video of it in action below and read on for more details…
Are you worried that you’re not paranoid enough about your communications security and want to improve your OpSec? Edward Snowden says to trust in encryption, but you still need to worry about the systems that run it:
Encryption works. Properly implemented strong crypto systems are one of the few things that you can rely on. Unfortunately, endpoint security is so terrifically weak that NSA can frequently find ways around it.
One step towards going “Full-Snowden” is with hardware storage of your PGP secret keys! The Yubikey Neo and Neo-N USB tokens are a neat (and not too expensive) way to keep the secret part of your RSA2048 keys locked in a hardware device rather than stored as a file on your harddrive. The hardware tokens are compatible with the OpenPGP card protocol, which recent versions of gnupg support out-of-the-box. All of the public-key cryptography happens inside the tamper-proof device, so your secret key is never decrypted in the memory nor stored on disk of your machine.
Since setting up the key pairs and transferring the secret ones to the device can be tricky the first time, I wrote a brief guide to configuring Yubikeys as OpenPGP crypto-hardware tokens. They integrate nicely with Apple’s Mail.app (or mutt with gpg-agent), so there is one less excuse for not protecting your email.
Last Friday was the Hack Holyoke 24-hour embedded systems hackathon, held at Mt Holyoke College. Of the 200 participants, well over half were women from the Seven Sisters schools and many were attending their first hackathon.
You can read @HackHolyoke twitter stream and read on for some photos of a few of the teams.
I 3d printed these boss headphone ear pieces for my sony mdr v6s. They are bad. Like 1980s power glove bad. You know it. #hashtag
